FREDERICK G. SARGENT, OF WESTFORD, MASSACHUSETTS.

WOOL-WASHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 223,393, dated January6, 1880.

Application filed October 19, 1877.

To all whom 'it may concern Be it known that I, FREDERICK G. SAR- GENT,of Westford, in the county of Middlesex and State of Massachusetts, haveinvented certain new and useful Improvements in Wool- Washing Machines,of which the following is a description.

rEhe object of my invention is to provide a wool-washing machine whichshall operate evenly, smoothly, and uniformly.

The nature of tlleinveution will fully appear from the subjoineddescription, when considered with reference to the accompanyingdrawings, forming part of this specification.

In the accompanying` drawings, in which similar letters of reference indica-te like parts,

Figure l is a longitudinal section. Fig. 2 shows the carrier.

A 1s the bowl of the machine. B is the inclined table; C, the rake. E isthe carrier. F is la cross-bar reaching from one side of the bowl to theother, and placed between the rake and carrier in such position as notto be within the path of either. To this cross-bar are attached fingersG, made of wire or other suitable material. From the bar they arecarried backward, gradually nearing the table, and when near theretocarried along parallel therewith for a considerable distance toward thesqueezerolls between the rows of teeth upon the carrier. D is the crankwhich moves the fork C, whose arm or staff C slides in the pivotedsleeve e. L is one of the rock-shaft arms, which is connected with theone upon the other end of the rock-shaftat its top by arod, upon whichthe rear end of the carrier E is supported. H is a central support forthe cranks D and K. J is a rigid arm attached to the carrier E andprovided with the hook a, which rests upon the pin of crank K.

The relative position of the shaft of cra-nk K, the inclined table B,rock-shat't arms L, carrier E, and arm J is such that the carrier willbe moved a greater distance on a line substantially parallel with thetable than it is upon a line perpendicular to it, while it is constantlysupported and moved by the crank, thus obviatin g the shocks and strainswhich a machine givingto its carrier an intermittent motion is subjectedto.

The bar F, being placed above the fluidlevel in the bowl A, will havethe wool crowded under it bythe fork C, and as the fingers G begin atthe bar F they will restupon the wool and press it down upon the ltableB; and as they are constructed of some flexible material they will serveto prevent the wool being thrown in large masses upon the table, wherethe tirst movement ot' the carrier will catch and carry it forwardtoward the squeeze-rolls 6o so quickly that it will not be evened outand spread as much vas is desirable to secure the most perfect operationof the rollers upon it. When the wool is crowded under the iingers thecarrier E, droppingits teeth between them near the bar F, moves forward,carrying the wool upon the table toward the squeeze-rolls; but thefingers, pressing down upon it with a pressure increasing` in proportionto the bulk beneath them, besides keeping back the larger 7o bunches, sothe teeth of the carrier will not catch into their greatest mass, serveto hold the wool back sufficiently to greatly even out any bunches whichthe fork U may deliver under the bar F, and as the fork O alwaysdelivers the wool to the carrier E in an irregular' manner, sometimesmaking amovement without delivering any and sometimes delivering twiceas much as should be allowed to go upon the table at once, my device, byholding back 8o y such large masses, permits the carrier to becontinuously operating upon the ber. In evening the sheet it movesforward to the squeeze-rolls, which therefore discharge the wool moreevenly and thoroughly squeezed and dried. The fingers G also serve thepurpose of holding the wool wherever the carrier leaves it to make itsreturn stroke, and thus avoid the use of teeth project-ing upward fromthe table over which the wool must be dragged 9o asitpasses towardtherolls; and as I construct the table of perforated metal the woolcontinues to drain as it passes up toward the roll while so held by thefingers, without having its liquor run back upon the wool lower downupon the table. One portion of the table make removable, so that thepart of the tank below it is more readily reached for examination orcleansing.

By constructing the crank K, bar J, and roo carrier E of the properrelative proportions, any desired backward and forward movement of thecarrier can be obtained with a innch smaller movement toward and fromthe table, and I am enabled, therefore, to obtain the proper andnecessary movement for the carrier while'directly connected With itsdrivingcranlz, and Without the use of guide and slide rods 01intermittent devices for moving the carrier.

By the above-described construction I am enabled to produce. aWool-washing,` machine which operates with less jar, more evenly, andwhich requires less power and less parts than rake-and-carrier machinesas heretofore 1 made.
